General Information
Term sinoatrial node development ID (Ontology) GO:0003163 (Gene Ontology)
Definition The process whose specific outcome is the progression of the sinoatrial (SA) node over time, from its formation to the mature structure. The SA node is part of the cardiac conduction system that controls the timing of heart muscle contraction. It relays electrical signals to the AV node.
Also Known As "SA node development" ; "SAN development"
